json_schema_validator

View on drupal.org

This module integrates Opis JSON Schema with Drupal.

You can validate JSON data against a JSON schema that you define. This is very useful for validating the content of JSON fields.

The module is intended for developers. You will need to create a custom module to add your schema.

For instructions, see the module's README.md.

Related modules

If you are using older versions of JSON Schema, you do not need this module; Drupal core and composer already include justinrainbow/json-schema. You only need this module if you want Opis for support for recent versions of JSON Schema (v4 and beyond).

Although the json-schema library was dormant for awhile, people are now actively working on it again and support for more recent versions of JSON Schema (currently available only with Opis) are being added.

See the discussion at #3350943: Dependency evaluation for json schema validation.
